Kinds of Packaging Materials: Change-Control Checklist

by

Reference Standard: Relevant material and performance testing standards Kinds of Packaging Materials: Control the Approved Baseline For repeat orders, the kinds of packaging materials should be controlled as complete packaging configurations rather than broad material names alone. A change in the container body, lid, pump, thread, dimensions, or protective treatment can create a materially different package even when the general material family appears unchanged. A useful approved baseline therefore records what was actually accepted at sample or production approval. The catalog identifies several configurations that illustrate this distinction: the F311# food can uses DR-8 tinplate at 0.16 mm; S-GS001 combines a silicone body with a PP lid; P-GS016 combines a … 続きを読む

Why Do Silicone Travel Bottles Leak on Planes? A Molecular Analysis Reference Standard: ASTM D813 (Standard Test Method for Rubber Deterioration—Crack Growth) and FDA 21 CFR 177.2600 (Rubber Articles Intended for Repeated Use) A premium Silicone Travel Bottle Set fails not due to simple user error, but through a complex matrix of chemical permeation, biofilm adhesion, and dynamic mechanical resonance. When exposed to low-pressure aviation environments and aggressive cosmetic compounds, standard elastomers suffer from macromolecular swelling and shear stress tearing. Counteracting these forces requires food-grade Liquid Silicone Rubber (LSR) with post-curing treatments, co-molded polypropylene (PP) collars, and precisely engineered cross-slit valves. To guarantee long-term stability in aggressive operational theaters—such as … 続きを読む
